At 12 57, Tina cycled from the mosque towards the mall while Winnie cycled from the mall towards the mosque. At 13 17, the two cyclists passed each other. 8 minutes later, Tina reached mall but Winnie was 1188 m from the mosque.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the mall and the mosque in km.
(a)
From 12 57 to 13 17 = 20 min
Combined speed of the two cyclists
= 1188 ÷ (20 - 8)
= 99 m/min
(b)
Distance between the mall and the mosque
= 20 x 99
= 1980 m
1000 m = 1 km
1980 m = 1.98 km
Distance between the mall and the mosque = 1.98 km
Answer(s): (a) 99 m/min; (b) 1.98 km
